UNITED STATES PATENT OFFICE.

COMBINED ENVELOP AND LETTER-SHEET.

Specification of Letters Patent.

Patented Sept. 12, 1905.

Application filed December 5, 1904-.- Serial No. 235.567.

To n whom it may concern:

Be it known that I, CHARLEs T. PADEN, a citizen of the United States, residing at Cheyenne, in the county of Laramie and State of WVyoming, have invented a new and useful Combined Envelop and Letter-Sheet,of which the following is a specification.

This invention relates to combined envelops and letter-sheets.

The object of the invention is to provide a simple and thoroughly effective envelop and letter-sheet or circular folder inwhich the employment of an adhesive of any kind for holding the folder portion combined with the envelop when folded is obviated and in which the contour of the flaps of the envelop are relied upon solely for this purpose.

The invention is intended more particularly for advertising purposes where an open envelop and one-cent postage are desired and where provision is made for inspecting the interior of the folder or letter-head Without opening the envelop. Both the envelop and the letter-sheet or folder portion can be utilized for advertising purposes, and also the letter-sheet portion can be utilized to inclose an envelop for return answer, if so desired.

The device can be made of any size desired and without waste of material, and will require no intricate or special type of machinery in its production.

The invention consists in the novel envelop and letter-sheet or circular folder hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like characters of reference indicate corresponding parts, Figure 1 is a view in plan of the combined envelop and letter-sheet as it appears before folding. Fig. 2 is a similar View of a slightly-modified form of the device. Fig. 3 is a perspective detail view exhibiting the form of folder shown in Fig. 1 folded for transmission through the mail.

As above stated, one of the essential features of the invention is to obviate the employment of an adhesive for holding the folder or letter-sheet together while being mailed and also to permit inspection of the interior of the device without opening it.

The results obtained are secured by providing the letter-sheet or circular-folder 1, which forms the body of the device, with two lateral flaps 2, the points of juncture between the flaps and the body forming right angles, as clearly shown in Fig. 1, the structure as a whole being T-shaped. In this figure the flaps are shown as rectangular; but in Fig. 2 the flaps 3 have their corners cut away, as at 4; but the points of juncture between the flaps and body portion 1 in both cases form right angles. The body portion and the inside of the envelop may contain printed matter of any description, and when folded, as shown in Fig. 3, the flaps are tucked in at the ends, and by reason of the right-angular disposition of the flaps with relation to the body they will positively hold the body folded against accidental opening while being mailed or handled.

In preparing the device for mailing it may be folded along the dotted lines shown in Figs. 1 and 2, these not forming any part of the invention and not being, in effect, present in the finished device, and when the body has been folded, as shown in Fig. 3, the flaps will then be tucked in.

It will be seen that by disposing the flaps at right angles to the body of the device a positive lock between them and the folds of the sheet will be effected which will be positive in holding the package from unfastening. By dispensing with the employment of an adhesive for holding the flaps combined with the body not only is the cost of production of the article materially reduced, but the labor necessary for moistening the adhesive and combining the flaps with the body is also rendered unnecessary.

Having thus described the invention, what is claimed is A device of the class described comprising an oblong imperforate body portion having lateral imperforate rectangular flaps forming right angles in conjunction with and having their upper edges constituting a continuation of the body portion, the peripheries of the body portion and the flaps being devoid of projecting portions.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

CHARLES T. PADEN.
